Not more than 80 years ago the mighty Colorado River flowed unhindered from northern Colorado through Utah, the Grand Canyon, Arizona, and Mexico before pouring out into the Gulf of California. But as one can see in this image of the Colorado River Delta taken on September 8, 2000, by the Spaceborne Thermal Emission and Reflection Radiometer (ASTER), flying aboard the spacecraft, irrigation and urban sprawl now prevent the river from reaching its final destination.The Colorado River can be seen ...

Namib-Naukluft National Park is an ecological preserve in the Namib Desert in southwest Africa, thought to be Earth’s oldest desert. The park is the largest game park in Africa, and a surprising collection of creatures manages to survive in the hyper-arid region, including snakes, geckos, unusual insects, hyenas, and jackals. More moisture comes in as a fog off the Atlantic Ocean than falls as rain, with the average 63 millimeters of rainfall per year concentrated in the months of February and...

The Missionary Ridge Fire, 10 miles north of Durango, Colorado, has been burning since June 9. By July 4, 2002 the fire had consumed almost 73,000 acres in the San Juan National Forest, and destroyed 56 homes. At that time the blaze was 55 percent contained, but still threatened several subdivisions. This Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) image combines daytime and nighttime images acquired on June 30, 2002...

About 50 miles north of the Washington (U.S.)-British Columbia (Canada) international line, a devastating wildfire has been burning in the Okanagan Mountain Park for several weeks. Tens of thousands of people have been on and off evacuation alert during that time, as the fire flares and subsides in response to varying terrain and weather conditions.As of September 5, 2003, nearly 3200 people in the southeastern part of the city of Kelowna were ordered from their homes as the 23,000-hectare (~57,...

| Dagze Co, Tibet - Image courtesy NASA/GSFC/MITI/ERSDAC/JAROS, and U.S./Japan
Dagze Co (Lake) is one of many inland lakes in Tibet, with a present area of 260 km2 (100 square miles). In glacial times, the region was considerably wetter, and lakes were correspondingly much larger. Changes in climate have resulted in greater aridity on the Tibetan Plateau. The numerous concentric rings that circle the lake are fossil shorelines, and attest to the historical presence of a larger, deeper lake.The image covers an area of 36.4 x 30.5 km, and was acquired by the Advanced Spacebo...

| Santorini Volcano, Greece - Image courtesy NASA/GSFC/MITI/ERSDAC/JAROS, and U.S./Japan
This image of Santorini Volcano in the Aegean Sea was taken by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), flying aboard NASA's spacecraft. The image was taken on November 21, 2000, and covers an area of 18 by 18 km. The eruption of Santorini in 1650 B.C. was one of the largest in the last 10,000 years. About 30 cubic kilometers of magma was erupted, forming a cloud of volcanic ash and rock (called a plinian column) 36 km high...

| Manaus, Brazil - Image courtesy NASA/GSFC/MITI/ERSDAC/JAROS, and U.S./Japan
The above image was acquired by the Advanced Spaceborne Thermal Emissions and Reflection Radiometer (ASTER) aboard NASA?s satellite and shows the junctions of the Amazon and Rio Negro rivers in Manus, Brazil. The Rio Negro flows 2300 kilometers (1400 miles) from Colombia to Brazil and appears dark blue in the image. The river gets its color from the high levels of tannin in the water. The waters of the Amazon River contain more sediment and appear purple and brown in the image...

The city of Boston has grown dramatically since its settlement in the 17th century. As seen in this map drawn in 1838, downtown Boston was a peninsula surrounded by several large islands and headlands along the Charles River. During the past 170 years, much of Boston Harbor and the mouth of the Charles River were filled in to create buildable land. The ASTER simulated natural color image depicts a large metropolis where land area dominates water...
